UNITED STATES' ANDREW LA FAYETTE BABRINGER, OF STATESVILLE, NORTH CAROLINA.

TRAIN-LINE CONNECTION.

Application led April 21,

To all 'whom t may concern.

Be it known that I, ANDREW LA FAYETTE BARRINGER, a citizen of the United States, and a resident of Statesville, in the county of Iredell and State of North Carolina, have invented certain new and useful Improvements in Train-Line Connections, of which the following is a specification.

My invention is an improvement in train line connections, and has for its object to provide mechanism in connection with the train line of an air brake system, for permitting the lines on cars to be connected at either side of the cars without the necessity for entering between the cars, and for providing a double connection, either of which may be used, the connection being shiftable from the car or from the side of the car.

In the drawings:

Figure 1 is a top plan view showing the improved connection;

Fig. 2 is an end view of iFig. 1;

Figs. 3, 4 and 5 are sectional views showing the different positions of the valves;

Fig. 6 is a sectional view showingthe locking mechanism.

The present embodiment of the invention is shown in connection with two cars, indi- ,cated at 1 and 2, the said cars having the usual couplers indicated at 3, for connecting them together, and each car carries a train pipe 4 extending beneath the car at one side thereof in the usual manner.

At each end of each of the train pipe sections there is arranged a valve casing indicated at 5, and in each casing there is a valve 6. Referring to Figs. 3, 4 and 5, it will be seen that each casing 5 has three ports 7, 8 and 9, respectively, and that the valve has a passage 10 for placing the ports in communication with each other. Each valve has a stem 11, with which is connected an arm or lever 12 for operating the valve in a manner to be presently described. The port 9 of each valve casing is connected with the train pipe 4.

To each port 8 there is connected a pipe 13 arranged upon the sill of the car and extending toward the opposite side of the car. The port 7 of each casing has connected therewith one of the sections 14 of a sectional air brake line connection of usual form. The other section 15 of each of these connections is on one end of a flexible hose 16, whose opposite end is connected with the Specification of Letters Patent.

pipe 13 at the end remote from the valve by means of an elbow 17.

By means of the passage 10 of the valve the ports 7 and 9 may be connected, as shown in Fig. 3, or the ports 8 and 9 may be connected as shown in Fig. 5. By turning the valve so that the passage is parallel with the axis of the ports 7 and 8, all of the ports are disconnected, so that the air is cut oil from the pipe 13 and from the hose 16.

When the valve on the car 2 is in the position shown in Fig. 3 the pressure passes from the train line 4 by way of the coupling 14-15 and the hose 16 at the left of Fig. 1 to the pipe 13 of the car 1. If the valve of the car 1 is arranged in the same manner, the pressure passes from the pipe 13 to the train line section 4 of the car 1.

If the valve on the car 2 is arranged in the position of Fig. 5 the pressure passes from the pipe 4 to the pipe 13 of the car 2, and by way of the hose 16 at the right of Fig. 1, to the, valve 5 on the car 1, and thence to the train line section 4. Thus with the valves the pressure may pass through either connection, that is, through the pipe 13 at the bottom of yFig. 1 and the hose 16 at the right of the said figure, or through the hose 16 at the left of the said igure and the pipe 13 at the top.

A link 18 is arranged substantially parallel with each pipe 13 and each end of the link is connected to the adjacent car by means of swinging arms 19. The handle 12 of the adjacent valve 6 is connected to the adjacent link 8 by means of a loop 20, as shown in Figs. 1 and 2, so that when the link 18 is moved longitudinally the handle 12 will be moved therewith, and the valve may be shifted in either direction.

Means is provided in connection with each swinging arm 19 for holding said arm in adjusted position. The said means consists of a notched bar 21 which is secured to the car beneath each arm, and each arm has a tooth or lug 22 for engaging one of the notches. The arms are sufficiently resilient to permit the tooth to slide from one notch to the other, and it will be evident that by moving the link 18 of either car in either direction and from either end of the said link the valve connected therewith may be shifted as above mentioned. This shifting may be done from the side of the car without the necessity for stepping between the cars or it may be done from on the car. Shoulda coupling lll-15 or the hose at either side be disabled that at the other may be used. There is alvvays'provided a double connection and a double route for the pressure, either of Which may be used.

I claim:

l. In combination With a car and the train pipe section thereof, of a lvalve casing at each end of the said section, a cross pipe extending transversely of the car at each end thereof and connected at the adjacent end to the valve casing, a hose connected WithA the other end of each pipe, said hose carrying one section of a coupler and the valve casing carrying a coperating section at the opposite side of the casing from the cross pipe, and a valve in the casing having a passage for placing either the crossv pipe or the last named coupling section in communication With the train pipe section, and means for shifting said valve fromweither side of the car and-for holding it in adjusted position, said means comprising a link, swinging arms connected With the car and to the link, said valve having a handle connected 'With the link, each swinging arm having a tooth, and` the .car having a'latch bar' provided with notches for engagement bythe tooth.

2. In combination with a car and the train pipe section thereof, of a valve casing at each end of the said section, a cross pipe extending transversely of the car at each end thereof and connected at'the adjacent endto the valve casing, a hose connected with the other end of each pipe, said hose carrying one section of a coupler and the valve casing carrying a cooperating section at thev opposite side of the casing from the cross pipe, a valve `in the casing having a passage for placing either the cross pipe or the last named coupling section in communication With the train pipe section, and means for shifting said valve from either side of the car and for holding it in adjusted position.

3. In combination With a car and the train pipe section thereof, of a valve casing at each end of the said section, a cross pipe extending transversely of the car at -each end thereof and connected at the adjacent end to the valve casing, Aa hose connected With the other end of each pipe, said hose carrying one sectionof a coupler and the valve casing carrying a coperating section at the'opposite side of the casing from the crosspipe, and a Vvalve inthe casing having a passage for placing either the cross pipe or the last named coupling section in communication with the train pipe section.

4. In combination with a car and the train line section thereof, of coupler sections at each endl of the train line section disposed adjacent the sides of the car to permit connection of either coupling section With a cooperating coupling section of another car Without entering betvveenthe cars, valves at opposite ends of the train line section for controlling the passagevof air to and from the coupler sections, and means Voperable from .either side ofthe car for actuating said valves.
